28 Claims.

'This invention relates to improvements in razors and razor blades and has for one of its objects to provide an improved razor of the magazine type for separate blades.

A further object is to provide a simple and eilicient positive means for feeding the blades from the magazine to the razor head inf/proper shaving position and ejecting the used blade therefrom by the mere manipulation of a single simple control member.

A further object is to provide a simple and efiicient positioning means, which when cooperating with a correspondingly formed blade, makes it possible to feed the blades to proper shaving position and eject the used blades therefrom without disturbing the relationship of the clamp cover to the blade seat, thus eliminating a separate additional operation and mechanism necessary for such an operation.

Another object of the invention is to provide a novel form of preformed razor blade, the cutting edge portion of which is permanently so disposed with relation to the mean plane of the main body portion as to have the effect of an abruptly downwardly turned cutting edge portion, for the purpose of insuring a relatively acute angle approaching parallelism with respect to the surface to beshaved when the blade is carried by a razor held at a convenient angle while shaving.

A further object is to adapt the magazine razor to the feeding of any type of blade, whether they be permanently flat, curved longitudinally or transversely or both or whether they are extremely flexible, inA which latter case the razor is adapted to feed them to the shaving position whether the cover and seat are at or curved or turned longitudinally or transversely or both.

Referring more particularly to the drawings, it

2o is to be understood at the outset that the present invention includes certain features disclosed in our copending applications, namely, for Safety razors, Serial Number 735,547, filed July 17, 1934. now Patent No. 2,053,642 dated September 8.

25 1936, and hereinafter referred to as application A, and for Safety razor, Serial Number 22,520, filed May 21, 1935, and hereinafter referred to as application "B.

For instance, the razor is of the general type 30 shown in application B in that it has a magazine for separate blades and means for successively feeding the blades to the blade seat and thence to the proper shaving position. The blade seat and blade may also be preformed to assume 3l the curvature, either longitudinally or transversely or both, described in application B, or the blade, guard or cover or all may have a more pronounced curvature or turned down effect transversely adjacent the shaving edge, as will 40 hereinafter be pointed out with greater particularity. The blades may likewise have the same degree of flexibility longitudinally and transversely throughout as described in application A. Moreover, the blades, insofar as the positioning slots, grooves or apertures are concerned are interchangeable.

'Ihe magazine razor, itself, is so constructed that the feeding of blades from the magazine to the proper shaving position and the ejection of so the used blade from the razor head are both accomplished by the simple turning of a knurled rotatable knob. 'Ihe razor may be said to include a casing with sections I, 2 and 3, divided by partitions 4 and l, sections I and 3 having upper l5 and lower walls 6 and 1 respectively.

Section 2 constitutes the watertight magazine in which a plurality of blades 3 are shown arranged on their ends. Instead of inserting these blades separately in the magazine we may prol0 vide a blade clip as shown in Figure 3. 'Ihis clip has an end wall 3 with upper and lower walls I l and II, slotted to receive a spring leaf I2. The magazine has a door I3 hinged at I4. When the door is moved to the position shown in dotted lines the clip full of blades is inserted in the magazine after the leaf I2 has been removed. The upper and lower walls I0 and I I have grooves Il and I3 to engage projections I'I and I3 on the partitions 4 and I to properly align the clip as it 70 is placed in the magazine with the wall l towards the hinged door opening. 'I'he wall 3 has an aperture I3 to permit the free passage of a plate 23. This plate thus engages the face of the nearest blade, and under the action of the compression coil spring 2|, forces the blades to the left, as viewed in Figure 1 so that a number thereon is visible through the glass enclosed watertight peep hole 90. A suitable pivcted handle 22 connected to bolt 25 carrying the pressure plate is operated for contracting the spring 5 2| while refilling the magazine. The upper and lower walls I0 and II are provided with inner flanges 23 and 24 to form guideways for the blade ends.

'I'he razor head includes a blade seat 23, guards 10 2'I4 and a cover 28 normally resiliently actuated to clamp the blade on its seat. The razor head, as shown in full lines, is in proper shaving position. 'I'he razor head includes a hollow tube 23 which is movable pivotally and rotatably in the l5 bearing 33 formed in the upper plate 6. Its pivotal movement is possible by means of the tube being pivotally connected at 3| to the casing. The tube also carries an arm 3|' on which is arranged a gear quadrant 32 adapted to mesh with 20 a pinion 33 on the upper end of a rotatable shaft 34 having suitable watertight bearings in partitions 4 and 5. A rotation of the shaft 34 in a counterclockwise direction moves the razor head pivotally from the position shown in full lines to that shown in dotted lines and a clockwise rotation of the shaft correspondingly` returns the razor head to its normal shaving position. The purpose of this pivotal movement is to align the space 33' indicated in dotted lines with the aper- 30 ture 84 in the partition 4 and consequently in alignment with the razor blade situated at the extreme left of the magazine. An upward movement of this blade under positive pressure forces the used blade off and forces the new blade into 35 shaving position. Thus when the razor head is returned to horizontal position the new blade is in proper shaving position. The blade shown in Figures 12 and 13 is provided with an elongated open end slot 36 to cooperate with a stud 36 of l0 corresponding width, as shown for instance in Figures 1, 2 and 22 to 27 inclusive, to properly position the blade on its seat. In order to use this type of blade and seat or the seat 23 of Fig.

20 to which the spring clamp cover 23 is fastened, 5 it will be readily realized that in moving the razor l head from the horizontal to the vertical for feeding a new blade to the head, the latter must be rotated 180 degrees. 'Ihis is because the open end slot of the used blade must be adjacent the opening 84 and adjacent the upper or open end slot of the new blade so that as the new blade is fed, the used blade is pushed otf of its seat.

'I'his rotative movement is made possible by means of the following construction: Secured to the casing is a stationary quadrant gear 33 adapted to mesh with a pinion 39. This pinion is carried by a shaft 40 which carries the seat 23 and which is rotatably mounted in the tube 23. As previously described a counterclockwise rotation of the pinion 33 causes the head to pivot from the horizontal to the vertical. Simultaneous with this movement, the pinion 39, meshing with quadrant 33, causes the head to rotate clockwise for 180 degrees. The shaft 40 carries a pawl 05 4I spring pressed outwardly by spring 42 forcing the pawl 4I to engage with the shoulder 43 on the inside of the pinion 33, permitting clockwise rotation to this extent. A reversal of this movement is prevented by the disengagement of the pawl 4I as it is forced away from the shoulder 43 on the inside of the pinion 33 as the pinion is moved in the reverse direction.

The movement ofthe shaft 34 is brought about by the simple manual rotation of a knurled knob 44 fixed to a rotary drum 4l, which bears on a journal 6' projecting from the wall 6. The gear quadrant 46 is carried by the drum and meshes with a pinion 41 on the lower extremity of shaft 34. This knob is rotatable in either direction but obviously no rotation is imparted to shaft 84 unless the quadrant 46 and pinion 41 are in mesh.

The rotation of the knob, besides rotating and pivoting the razor head,-also effects a feeding of the blade from the magazine into the proper space 33' in the head. The drum 45 is provided with an exteriorly arranged groove or flange of predetermined spiral and flat portions 48 and 48. As shown in Figure 4, one wall 3 of the lower section 3 is formed with guide members 50 and 5I for a sliding plate 52, which latter may have tongues 53 and 54 iitting in corresponding vertical grooves in the inner surface of the wall il'. This arrangement insures alignment of the vertically movable slide. 'I'he slide is of a height equal to section 3 so that an upward movement thereof forces the blade at the extreme left of the magazine upwardly. The slide is preferably of the same thickness as the blade so that it moves only one blade at a time. Accordingly the slide should also be of a height at least as great as the height of section 2 plus the thickness of walls 4 and 5. Fixed to the slide 52 is a pin 55. As long as the pin is in engagement with the fiat portion 48 of the groove no vertical movement is imparted to the slide 52. However, upon l rotation of the drum 45 to such an extent that the pin engages the spiral groove 46, the drum upon clockwise rotation forces the slide upwardly. Accordingly a counterclockwise rotation of the drum lowers the slide. It should be observed that should the operator attempt to lower the slide before completing its function of feeding the blade, this will be prevented by the blade being only partially fed into the razor head and thus holding the head against movement and preventing the counterclockwise rotation of the drum which controls the movement of the slide.

The location of the quadrant 46 and pinion 41 and the relationship of the pin 55 and grooves 49 and 48 is such that the movement of the slide 52 is entirely independent of the pivotal or rotative movements of the razor head even though all of these movements are brought about by a manual control of the single operating knob 44.

It will be observed that when blades such as are shown in Figures 8 to 11 and 14 to 17, inclusive, are used in such a magazine razor as ours, it will be necessary to x the clamp cover on the exterior of the blade seat in such a way as not to obstruct the passage of the blade between the clamp cover and the seat. One method of doing this is shown in Figures 20 and 21 where the clamp cover 28 is fixed to the seat 26 at its outwardly disposed ends 35 thus permitting free passage of the blade 8. However, it is not considered that such an arrangement of the clamp cover is sufcient means for positively positioning and maintaining the blade on its seat. Therefore, we provide such means that will positively seat the blade in propr shaving position in relation to the guard, independently of the guard. For example, Figure 18 shows a blade seat 26 with a groove 59 to Aaccommodate the blade shown in Figures 8 and 9. Figure 19 shows a seat 26 with a longitudinal stud 31 to accommodate the blade shown in Figures 16 and 17. The stud may also be of a disappearing stud type such as shown at 6| in Figure 28, and

which will be more particularly described hereinafter. With such a type of disappearing stud as shown in this Figure 28, the ejection of a blade from the head, without removing the clamp cover as is necessary in conventionally used razors where positioning studs are used, is made possible, for, as the blade is pushed forward over the cam like end 6I' of the stud 6I and then out of the head by the incoming blade the stud is urged down into the countersunk portion 66, Figure 28, and permits the free passage thereof. With this arrangement the head will not have to be rotated 180 as before described and the pinion 39 and quadrant 36 may be dispensed with if desired.

'I'he blades 8, for purposes oi' illustration may be considered to be iiexible to the extent described in our application A. Instead ofv having the blade seat shown fiat as in Figure 2, and which is shown flat for the purpose of simple illustration, it may be curved transversely or of any other desired shape. However, in the case wherea transversely curved blade seat is used of the conventional type and flexible blades such as described in our application A, in order to easily feed such blades to such a curved blade seat and clamp cover in the same manner as described in connection with Figure 1, we have shown a suitable construction in Figures 5 and 6. In the wall 2 of section 2 near the top thereof may be formed an inclined and convexly curved groove 56 so shaped that as the blade is pushed upwardly it assumes the proper convex transverse curvature corresponding to the blade seat and cover and the space therebetween.

For the general type of blade seat shown in Figure 19 having a single or a plurality of positioning projections 31 thereon, we have illustrated several examples of blades in Figures, 10 to 17 inclusive with cooperating elements to engage the positioning projections. For instance the blade instead of having the open end slot 36 may have the groove 51 of Figures 16 and 17 or a combination thereof as shown in Figures 14 and 15 to accommodate the feeding operation previously described. Obviously the blade seat may be provided with a groove 58 to accommodate a projection 58 on the blade as shown in Figures 8, 9 and 18. If desirable, the blade may, of course, be provided with a plurality of apertures 60 to cooperate each with a plurality of studs such as 6I in Figure 28, wherein the positioning element of the blade seat may take the form of a member 6| with a leg or legs 62 and 63 extending through the blade seat 26 with enlargements 64 and 65 to prevent removal. 'Ihe member 6l fits in a countersunk portion 66 in the blade seat and is normally resiliently upwardly urged by the springs 61 and 68. These various forms of cooperating positioning elements of the blades and blade seats are in no way dependent upon the flexibility or rigidity of the blade nor upon the longitudinal or ltransverse disposition of the blade, curved or otherwise, whether preformed or distorted when clamped in the razor head. The point is that inasmuch as these features are interchangeable the actual illustration in the drawings is not burdened with a possible muititudinous series of combinations.

Now lin addition to the foregoing discussion and description it has come to our attention that while some blades and holders do provide for a limited degree of transverse curvature they do not provide for a. proper disposition of the shaving edge with respect to the surface to be shaved. For instance as illustrated in Figure 29 the sur- In Figure 24 the shape of the blade, blade seat face to be shaved is illustrated at B. The hair may be presumed to be extending laterally at right angles to the surface. In order to effectively cut these hairs for a clean shave the cutting edge portion of the blade should be substantially parallel to the surface S and hence appreaching at right angles to the hairs. We have found that the usual angle of holding the razor handle adopted by the user for arm comfort is about the angular position as shown at A. However, when held at this angle the blade of the present conventional types of razors are not at the effective angle. By way of comparison, in order to dispose the razor blade'cutting edge properly it would be necessary in the case of a moderately transversely curved blade to hold the handle in the attitude illustrated at B, and in the case of a straight ilat blade, at the attitude illustrated at C. To overcome these disadvantages we propose to so dispose the cutting edge portion of the blade with respect to its main body portion that the handle may be held in the convenient comfortable attitude shown at D and at the same time insure the disposition of the blade so that the cutting edge portion will be substantially parallel to the surface and therefore substantially at right angles to the hairs thereon.

The arrangement shown in Figure 22 includes a blade, blade seat and cover of the conventional type moderately curved transversely with a conventional guard. For the purpose immediately previously described we may adopt any of the arrangements shown in Figures 23 to 27 inclusive or any other blade shape arrangement which produces the same result. For instance in Figures 23 to 27 inclusive the blade is preformed to rigidly maintain the shapes illustrated, the blade in each case being in proper` shaving relationship with the guard and protruding a substantial distance past the edge of the clamp cover. In Figure 23 'the guard is turned down providing a curved surface 31* to conform with the curved surface 8'* of the blade, the remainder of the latter being moderately convexly curved transversely or any other desirable shape. The illustration in Figure 25 conforms to that shown in lFigure 23 with the exception that the main body portion is substantially flat transversely. In Figure 26 the main body portion of the blade is moderately curvedtransversely while in Figure 27 it is fiat. In both Figures 26 and 27 the edge of the guard, being abruptly turned down, is provided with an angular surface 31h to conform to the angular turned down edge 8 of the blade.

and guard are the same as shown in Figure 23. To accommodate a flexible blade of such type as described in our copending application A and support the same, however, the clamp cover 28 may be extended to be abruptly downwardly curved as at 28. It obviously follows that the clamp cover could be extended in any of the arrangements shown in Figures 25 to 27, inclusive, equally as well for supporting flexible blades in the manner shown for supporting preformed rigid blades.

In each of the cases shown in Figures 23 to 27, inclusive, the cutting edge is predeterminedly abruptly turned down to such an extent that as the user holds the handle at approximately the angular position shown at D, with respect to the surface S, Figure 29. the shaving edge of the blade will be disposed substantially parallel to the surface S and therefore at right angles to the hairs.

The above described feature eliminates the necessity for the user to hold the razor at an inconvenient angle. It further does away with the head may be dispensed with in the event the cooperating positioning elements of the blade and head are of such a nature as to make such a rotation unnecessary. 'I'he modification of the actual structure shown would involve only the elimination of the stationary quadrant gear of the head.

Likewise the inclined and convexly curved groove 56 for bending the exible blade may be made so as to be removably installed in the razor for taking care of the flexible blades as described. The aperture, or more aptly, the slot M may be predeterminedly formed to correspond to the transverse dimensions of the blade, whether the latter be transversely flat, curved, curved and flat or angular for different extents of its transverse dimensions.
